I did change this in a previous release to ensure that when using the option to hide the form label column it would not flash before vLookup is loaded. I see that this can make it look a bit strange if you don’t use a header above your vLookup field.
I’ll make a change in the next release to only initially hide the label if the vLookup field has not been renamed and the display name still starts with “vLookup”.
